FELLY-TROUGH.

SPECIFICATION forming part of Letters Patent No. 630,481, dated August8, 1899. Application iiled June 13, 1898. Serial No. 683,324. (Nomodel.)

To all whom it may concern:

Beit known that I, FRANZ S. BRIGGS, a citizen of the United States,residing at Neosho, in the county of Newton and State of Missouri, haveinvented a new and useful Trough for Boiling Fellies, of which thefollowing is a specification.

The invention relates to improvements in troughs for boiling fellies.

The object of the present invention is to improve the construction oftroughs for boiling fellics in oil and to provide a simple, inexpensive,and seamless trough adapted to be constructed of a single piece of.sheet metal and provided with a smooth bottom and sides r to preventaccumulation of hardened iand burned oil on the interior.

A further object of the invention is to avoid soldering the parts and toprovide legs or rests for supplying a firm base to prevent the troughfrom tipping or spilling any of its contents While in use.

The invention consists in the construction and novel combination andarrangement of parts hereinafter fully described, illustrated in theaccompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure 1 is a perspective view of a trough constructedin accordance with this invention and shown in an upright position. Fig.2 isa similar view, the trough being inverted. Fig. 3 is a detailsectional view of one end of the trough. Fig. 4. is a longitudinalsectional View. Fig. 5 is a transverse sectional view.

Like numerals of reference designate corresponding parts in all i thegures of the drawings.

1 designates atrough'constructed of a single piece of sheet metal andcomposed of vertical sides 2 and a curved bottom conforming to theconfiguration of the fellies to be boiled and extending upward from thelower edges of the sides at the center of the trough to the upper edgesof the sides at the ends thereof. The trough is formed of an oblongblank, which is folded at equal distances from its side edges to providethe sides 2, and the intermediate portion between the sides is curvedupward between the same to form the bottomthe superiluous metal at thelower edges of the sides providing depending flanges L1,-which serve aslegs or rests and support the trough to prevent the same from tippingand spilling any of its contents Whilein use. The folded portions whichform the flanges 4 are compressed to bring the two plies or members ofeach ange close together, and the ends 5 of the flanges are folded backon the exterior of the sides, thereby firmly securing the parts andpreserving the shape of the trough.

, The upper edges of the trough may be provided with a seam tostrengthen the device, or the said upper edges may be rolled into beadsand supported by wires inserted in the beads in the usual manner.

The invention has the followin g ad vantages The trough, which hasacurved bottom to conform to the configuration of the curve of a wheel,is constructed of a single piece of sheet metal and Without soldered orsimilar seams, so that there is no liability of it dropping to pieceswhen heated. It is especially adapted for boiling fellies in oil, as itpresents smooth inner faces and prevents accumulation of hardened andburned oil on 'the interior. The fold or lap securely holds the troughin its proper shape and at the' same time provides depending flangeswhich form legs or rests and prevent the trough from tipping or spillingany of its contents While it is in use. The

arrangement and the manner of folding the parts permit the edges of thetrough to be i stiened by a seam or a bead.

What I claim isl. A trough constructed of a single piece of sheet metaland comprising a curved bottomand sides, the metal being folded at thejuncture of the sides'and bottom and forming depending flanges',substantially as described. l

2. A trough constructed of a single piece of sheet metal folded to forma curved bottomof a single thickness, and sides having danges dependingbelow the bottom and composed of two thicknesses of sheet metal,substantially as and for the purposeV described.

3. A trough constructed iof a single piece of sheet metal foldedlongitudinally to form vertical sides, and having the intermediate IOOportion between the sides curved upward lto l Intestimony'that I claimthe foregoing as form a bottom, the superfluous metal being my ownIhaveheretoaxed myignature in extended downward and forming continuathepresence of two witnesses.
